1 Claim. (CI. 41-26) The ready-made clothing industry is faced with the old problem of mechanically marking a curve on a workpiece, after which the latter has to be cut out.

The object of the present invention is to provide a solution of this problem and the invention consists in throwing a liquid dye (bleaching agent) against the templet and workpiece (piece of cloth) by means of a vertically arranged disc used in combination with a tube for the liquid dye through which the latter is conveyed, the disc being rotated by a motor.

One mode of carrying the invention into efiect is hereinafter described, by way of example, with reference to the accompanying drawings.

Figure 1 is a perspective view of the general arrangement mounted on shelves across the bench on a slider, which is slidingly mounted along the bench;

Figure 2 shows the disc in section;

Figure 3 is a perspective view of the disc; and

Figure 4 is a perspective View of a detail.

The arrangement shown in the drawings consists of a disc 6 constructed with a cup-shaped portion and secured to the shaft of a motor 7. A smaller disc 10 provided with a number of pins 9 is secured to the bottom of the cup 5 by a screw 11. The pins surround a jet nozzle 12 of a feed pipe 13 inserted between them. The nozzle is provided with a valve seat 14 cooperating with a valve plug 15. The latter is extended to the core 16 of a magnet coil 17, connected to a source of current 19 by a wire 18. The core is provided within the coil with a spring 20 which tends to press the core and therewith the valve plug against the valve seat 14. The core is suitably provided with a sealing member 21 in a casing 22 in order to prevent flow of the liquid dye from the tube 13 penetrating into the magnetic coil. The tube is provided with a cock 23 and is connected to a receptacle 24 mounted on a shelf 25. The disc 6 is partly connected to a splashing member 26 which is open downwards (see Figure 3) towards a work bench 27. The shelf supporting also the motor 7 is slidingly mounted by means of pulleys on a slider 29 which in its turn slides by means of wheels 30 on rails 31 provided along the bench. The slider 29 is provided with two transverse rods 32, 33, in tended to be raised from or lowered towards the work piece on the bench by means of a lever 34, the space left free between the said rods lying exactly below the disc 6.

The arrangement illustrated in Figure 1 shows the apparatus described above in duplicate and running parallel with one another.

The operation of the arrangement above described is as follows:

After the templets 36 have been placed on the bench 27 and held in position by a netting 42, the rods 32, 33, are lowered against the templets by the lever 34 (the position shown in the figure) and the motor is started through the intermediary of a starting rheostat 37 and the disc is rotated. When a push button 38 is pressed down the coil 17 is energized and the core 16 is attracted so that the valve plug frees the valve seat and the liquid dye spurts in between the pins 9 and is thrown against the disc 6 and therefrom whilst being continuously thinned out it passes through the opening of the splashing member down against the bench and the templets so that the latter are marked against the work pieces under them.

The liquid dye which is thrown against the splashing member runs through suitable discharge pipes 39 and gutters 40 down into a receptacle 41.

The disc 6 is of concave shape so that the liquid dye will follow its configuration before it is thrown out.

The arrangement hereinbefore described may also be used to its advantage for dyeing cloths.

It is to be understood that the invention is not limited to the construction hereinbefore described which may be modified without departing from the scope of the invention as claimed in the appended claim.

What I claim is:

A method of securing templets closely to a workpiece to which the contours of the templets are to be transferred by the ejection of a dye, comprising the following steps: placing a netting over the templet for securing the latter to a workpiece, having a series of closely adjacent rollers passing over said net, and spraying a die between said rollers and against the templets and workpiece.
